The feature of the products are anti-thief, long life, high accuracy, high reliability, low power consumption small volume, light weight, the meter is up to the according to iec 1036-96 and GB/t17215-200 standard.

1. Main Features:

● EnergyMeasurement

Total and time-sharing forward active & reactiveenergy measurement

Total and time-sharing reverse active & reactiveenergy measurement

Save last one to sixteen months energy data

● IC Card TransferSpecification

Credit data transfered from a point of sale (POS) orvending system is made into IC card using

the Standard Transfer Specification(STS) encryption techniques, which comply with IEC62055 protocol

● Load control function

When the residual energyis 0 or the allowable overdraft that both sides agreed, this meter will

sendout power-off signal to have load switch cut off power.

The power will berecovered automatically after inputting new purchased energy amount.

● Programmable low creditwarning

The meter can beprogrammed for setting user credit warning threshold,

When the meter's residualenergy is equal to credit warning threshold, the meter will start theaudio & video warning function in a way of warning light flashing
